Hashimoto's thyroiditis is a chronic autoimmune disease and is the most common type of thyroiditis clinically. Its etiology is primarily immunological, as Hashimoto's thyroiditis is an autoimmune disorder. Therefore, patients can detect a high concentration of anti-thyroid antibodies through blood tests, such as anti-thyroglobulin antibodies and anti-microsomal antibodies. Additionally, genetic factors are involved, with about 50% of patients with Hashimoto's thyroiditis having a family history. Environmental factors, including radiation, infections, excessive dietary iodine, and selenium deficiency, can also lead to Hashimoto's thyroiditis. In recent years, the incidence of Hashimoto's thyroiditis has notably increased.

How is Hashimoto's thyroiditis treated?

After being diagnosed with Hashimoto's thyroiditis, treatment decisions should be made based on the size of the thyroid and the presence of symptoms. If the thyroid is relatively small and there are no significant compression symptoms, it is possible to follow up and observe without treatment. If the thyroid is significantly enlarged and there are compression symptoms, thyroid hormone preparations can be used to reduce thyroid swelling. If there is hypothyroidism, it is necessary to use thyroid hormone or levothyroxine for supplementary replacement therapy. In cases of Hashimoto's thyroiditis with hyperthyroidism, short-term treatment should follow the treatment for Graves' disease, using antithyroid treatments such as thioamides or thioureas. (Medications should be used under the guidance of a physician, and self-medication without guidance is strongly discouraged.)

Can Hashimoto's thyroiditis be cured?

Hashimoto's thyroiditis is an autoimmune thyroiditis where the body itself has autoantibodies that lead to the destruction of thyroid follicular cells, resulting in the failure of thyroid cells. Therefore, Hashimoto's thyroiditis can manifest as hyperthyroidism, euthyroidism, and hypothyroidism. Ultimately, Hashimoto's thyroiditis may develop into hypothyroidism. Hypothyroidism is proliferative and generally cannot be completely cured, but clinical remission can be achieved through oral administration of levothyroxine. However, Hashimoto's thyroiditis cannot be completely cured and requires lifelong replacement therapy.

Hashimoto's thyroiditis is an autoimmune disorder that attacks the thyroid gland, leading to hypothyroidism.

Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, is an autoimmune disease. Some patients with Hashimoto's thyroiditis have normal thyroid function and generally do not require treatment, but it is recommended to regularly review thyroid function and have thyroid ultrasonography. Some patients with Hashimoto’s thyroiditis may also suffer from hypothyroidism, which can manifest clinically as fatigue, constipation, and edema. If these symptoms are present, it is advisable to visit an endocrinology specialist promptly, complete thyroid function tests, and use thyroid hormone supplements under the guidance of a doctor.

What is the heart rate for Hashimoto's thyroiditis?

Hashimoto's thyroiditis is an autoimmune thyroid disease. The course of the disease can include hyperthyroidism, euthyroidism, and hypothyroidism. When Hashimoto's thyroiditis is at different stages of thyroid function, the changes in heart rate are also inconsistent. When Hashimoto's thyroiditis coincides with hyperthyroidism, the heart rate may be fast, even exceeding 100bpm. When Hashimoto's thyroiditis coincides with normal thyroid function, the heart rate may be within the normal range, around 60bpm to 100bpm. When Hashimoto's thyroiditis coincides with hypothyroidism, the heart rate may slow down, possibly dropping below 60bpm. Therefore, in Hashimoto's thyroiditis, as the thyroid function varies, so does the heart rate.

Can you get pregnant with Hashimoto's thyroiditis?

Hashimoto's thyroiditis can lead to pregnancy, but the prerequisite is that you must visit an endocrinology specialist before pregnancy to check your thyroid function, ensuring that the TSH (thyroid-stimulating hormone) is controlled below 2.5. This situation is suitable for pregnancy because if TSH is greater than 2.5, it is likely to have a certain impact on the fetus's intelligence. Therefore, if you have Hashimoto's thyroiditis and are planning to conceive, you first need to check the thyroid function. If this indicator is normal, then you can consider pregnancy.
